Sleep and Stress Tests
Cortisol is a hormone that plays a vital role in the body's stress response. Testing cortisol levels typically involves a blood test, saliva test, or urine test. Each method has its advantages and limitations, and the choice of test depends on the specific situation and the preference of the healthcare provider or individual.
Why Measure Melatonin for Sleep Disorders
Melatonin is a hormone that plays a crucial role in regulating the sleep-wake cycle. Measuring melatonin levels can provide valuable insights into sleep issues for several reasons, as supported by scientific literature:
1. Sleep-wake cycle
regulation: Melatonin is
involved in regulating the
body's circadian rhythm,
which governs the sleep-
wake cycle. Abnormal
melatonin production can
lead to disruptions in this
cycle and cause sleep problems (Arendt, 2005). Reference: Arendt, J. (2005). Melatonin: Characteristics, concerns, and prospects. Journal of Biological Rhythms, 20(4), 291-303.
2. Sleep disorders: Some sleep disorders, such as delayed sleep phase syndrome (DSPS) or advanced sleep phase syndrome (ASPS), are associated with altered melatonin production and release patterns.
